Abstract

Different materials viz. alginate, κ- carrageenan and polyacrylamide gels were examined for immobilization of whole cells of Bacillus sp. PE-11 and used for the production of alkaline protease. The effect of alginate concentration, incubation time and curing time on alkaline protease production and stability of biocatalyst were investigated. The immobilized cells of Bacillus sp. PE-11 in calcium alginate are more efficient for the production of alkaline protease with repeat batch fermentation for 9 days.
